The main path going to Mount Purro Nature Reserve is currently under construction. Today my organization, Project LAAN, conducted a community mapping visit there, and we passed the bypass route linked below. Kindly add it as road please. I have added it to Open Street Map for your reference (https://www.openstreetmap.org/edit?editor=id#map=18/14.67322/121.24418).
